PArENToFF CARPET, RUG, AND FLOOR BRUSH. I 7

Application fil ed. July '31,

This invention relates to brushes and in particular to brushes adapted to be attached to vacuum cleaners for cleaning and wash- 1 ing rugs.

It is an object of the invention to provide a brush attachable to a vacuum cleaner with a support facilitating the movement of the fitting 12 attached to the suction pipe 13 of brush over the rug. Y

It is a further object of the invention to provide a brush having a support extending through the bristles of the brush and which will be adjustableso that the brush may be adjusted relatively to the surface which is being cleaned.

With the foregoing and other objects in view which will be more specifically pointed out in the following detailed description and defined in the appended claim, reference is bad to the accompanying drawings for an illustrative embodiment of the invention, wherein- Fig. 1, is a partial perspective showing the improved brush mounted upon a vacuum forming device.

Fig. 2, isv a front elevation of'the brush shown in Fig. 1, parts being broken away and shown in section. 1

Fig. 3, is a bottom plan view of the brush as shown in Fig. 2.

Figures 4, 5, and 6 are top plan, side elevation, and bottom plan views of a modified form of the invention.

Fig. 7. is a view illustrating the utility of the improved brush as shown in Figures 1 to 3 inclusive, when cleaning a carpet or rug.

Referring to the accompanying drawings 7 wherein similar reference characters refer to similar parts, the brush consists of a body 10 having an aperture 11 therein which is s be mounted upon the article to be supported,

adapted to register with the opening of a Y a vacuum forming means, such as that of the ordinalvacuum cleaner. Bristles B arearra'nged upon the underside of the body 10 around the edge thereof, so as to leave a central vacant or bare space" 14; upon the opposite ends of the body 10 are mounted suitable supports generally designated by the reference character 15.

The supports 15, consist of a threaded shank 16 having a wing nut or similar twisting device 17 secured upon its upper end and provided with a suitable socket 18 adapt- 1924. Serial No. 729,254.

ed to receive a ball 19 which bears against suitable smaller balls 20-disposed within the socket. The ball'19 forms an anti-friction device for thesupport 15 and+as shown, projects from between the bristles of the brush and bears upon the floor F. As a means for adjustingthe brush, the threaded shankextends through a threaded collar 21 secured upon the body 10 by means of screws be forced upwardly or downwardly through the body 10. A suitable lock nut .23 is 16 in adjusted provided which. has an adjustable support 'so that the bristles of the brush maybe raised or lowered relatively to the floor,

therebyprolonging the life of the brush.

7 In Figures 4, 5, and 6, the adjustable support is shown as being mounted upon a brush of ordinary construction. With reference, in particular, to Fig. 7 it is seen that when a vacuum brush having the adjustable supports 15 mounted thereon is moved 'over a carpet C, the carpet beneath the supports 15 is held in contact with the floor F. As clearlyshown in Fig. 7 the carpet G between the supports 15-may be lifted by suction of the vacuum forming means off of the floor.

so that air will be drawn directly through 22, so that as the shank 16 is rotated it will the carpet, thereby increasing the cleaning efiiciency of the brush.

It is to be understood that various changes may be made in the details'of. construction without departing from the spirit or scope of the invention as defined by the appended claim.

WhatI claim is:

Acaster comprising a member adapted to a shank threadedly "extending through said member, a handle rigid with one end of the shank by which the shank may be vertically adjusted with respect to said member, a

socket provided on the other end of the shank, a ball retained in said socket and rotatable therein, and a lock nut threaded
